FLOYD HAMBLIN, OF BOONVILLE, NEW YORK.

WASHING- MACHINE.

SPEOIFICATION formingpart of Letters iatent No. 223,728, dated January20, 1880. Application filed November 24, 1879.

To all whom it may concern Be it known that I, FLOYD HAMBLIN, ofBoonville, in the county of Oneida and State of New York, have inventeda new and useful Improvement in Washing-Machines; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

My invention relates to washing-machines of that class in which theclothes are passed between revolving rolls and cleaned by frictionalcontact therewith; and its object is to construct a more simple andconvenient machine than those of this class generally used, the rollsbeing so constructed that the possibility of injury to the fabric islessened, while the efficiency of the machine is increased.

Thein vention consists in the means for locking one of the rolls andholding it stationary when desired; and, further, in the construction,arrangement, and combination of the operative parts, all as fullyhereinafter explained.

In the accompanying drawings, Figure 1 is a perspective. Fig. 2 is acentral longitudinal section, and Fig. 3 is a detached view of thelocking device.

The machine is contained in 'a box or case, A, which may be of anydesired construction, but is preferably rectangular in shape, as shown.The case or box is mounted on four legs, suitably braced, and sufficientspace is left beneath the case for the admission of a drawer, B, slidingin Ways a a, and of sufficient capacity to hold a large quantity ofclothes. Within the case and on opposite sides thereof are twostandards, 0 O, secured to the bottomof the case and slottedlongitudinally, as shown, the greater portion of their length, and inthese slots are journaled a pair of rolls, D E, the journals of theupper roll, D, resting in grooves on the upper edge of the case.

Pins maybe passed through the slots in the standards to keep the upperroll in place. I

prefer to provide two slots in the standards,

in order that the position of the upper roll may be either exactly overthe lower roll or a little on one side, as shown in Fig. 2.

The upper roll is fluted, as shown. The journals of the lower roll, E,rest in the bottom of .the slots in the standards, and this rollisprovided with convex projections of such a size as exactly to fit theflutings on the upper roll.

The revolution of the upper roll will therefore revolve the lower rollin an opposite direction. Each of the rounded projections on the lowerroll is provided with one or more longitudinal grooves, b, which areintended to increase the frictional or feeding power of the machinewithout being deep or wide enough to pull or stretch the fabric.

It is usually the case, in the machines ordiua-rily used, that thecorrugated rolls have a tendency to pull and stretch the fabric passingbetween them. I" avoid this by making the elevation on one roll exactlyfit the corresponding depression on the other, so that the fabric issimply pressed between the two surfaces without any pulling orstretching. A crank-handle is attached to the upper roll, as shown, bywhich both rolls are revolved.

In washing heavy fabrics or-c1othes more than usually soiled it issometimes desirable to lock one roll in order to increase the friction.I accomplish this by means of a wheel, F, secured upon a pin or screwdriven into the inner side of the machine in close proximity to thelower roll, D. This wheel has a spur, c, on its inner face near theedge, which engages with slots d in the roll E when it is desired'tolock said lower roll.

The edge of the wheel F may he roughened, if desired, to give a betterhold for the hand in turning.

In order to maintain a continuous pressure of the upper roll on thelower, which shall also be yielding, I provide spring-fastenings G G.(Shown in Fig. 1.) They consist of apiece of wire, one end of which ishooked over the journal of the upper roll, and then, passing downthrough a staple, c, on the side of the case, is bent into ahelical'spriug, and the other end passed through the staple, andprovided with a hook for engagement with a stud, g, on the case.

It is not necessary to the operation of the device, under ordinarycircumstances, that the hook should be engaged with the stud; but

when the revolution of the lower roller is stopped, and it isdesirahle'to increase the pressure of the upper roll, it can be effectedby connecting the hook with the stud, giving a continuous pressure, atthe same time yielding to any inequalities in the cloth, or the at- Iootempted passage through the rolls of substances which might otherwiseclog them.

For convenience in washing delicate fabrics, which'might be injured bypassing between the rolls, I provide at one end of the case anadjustable wash-board, H, which, when not in use, is held in place byguides I I, so that it occupies very little space.

In use the board is elevated and supported on the rear edge of the caseby means of two diagonal grooves, h h, which hold it at the properinclination for use.

One of the principal advantages of my device'depends upon the shape ofthe rolls, by which a simple pressureis brought on the fabric and anystretching or pulling avoided.

Other advantages, which will be apparent to those skilled in the art,arise from its simplieity, compactness, the adjustahihty of its parts,and the cheapness with which it can be constructed;

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is. v

1. In a washing-machine, the combination of the roll D, the .roll E,having slots 01, the wheel F, and the spur c thereon, substantially asand for the purpose set forth.

2. The described washingnnachine, consisting of the upper fluted roll,D, and the lower roll, E, having convex projections, a helical springfor increasing the pressure of the upper upon the lower roll, and awheel and spur acting in connection with grooves in the lower roll forholding such roll stationary, substantially as described and shown.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FLOYD HAMBLIN.
